REFRIGERATED SEOW- CASE.

Application Ilefl July 25, 1925. Serial No. 46,042.

This invention relates to show cases, and ias special reference to a combination refrigerator, showcase, and worlr counter.

rllhe principal object of my present invention that of producing` a simple and ficient article of this character and one particularly designed with means for inahintaining a uniformly constant level of brine therein.

Another object is to provide novel means for caring for the refuse from the articles being displayed and preventing their being deposited within the brine.

Other objects and advantages of the peculiar combination will appear in the further description of the invention.

The accompanying illustration, in which lilre reference characters indicate like parts, is a vertical section through one of the improved refrigerated sh'ow cases. the longitudinal shape and dimensions of which are not material to the invention.

1 represents one of the fabricated pedestal supporting sections, the front of which, beneath the show case, may be paneled, as at 2, if desired. On top of tlis support rests the show case, comprising the pyramidally shaped portion 3 having glazed front and vbach sides, as at d and 5 respectively, and adjacent which latter' is the wcrlr counter 6. Beneath the work counter is a relatively deep chamber forming that portion of the refrigerating chamber iii which the ice or other cooling medium may be depcsited, and this cooling chamber extends forwardly be neath the display chamber 8 of the show case, the latter chamber being providedwith a removable bottom 9 spaced upwardly from the bottom 10 of the refrigerator space, and inclined slightly downwardly and forwardly so to drain into the refrigerator space.

rlhe bottom of this latter, and in Afact the entire show case, is inclined in the opposite direction towards the rearmost corner and suitably insulated in any desired manner.

Beneath the rearmost corner of the refrig erator space and huilt into the bottoni of the show case is a funnel-like drain tube, indicated at 11, and above'this drain tube, within the refrigerator tank `which forins the refrigerating space, is the upstanding crain tube 12, the saine being surrounded by suitable insulation 13 to prevent heat entering the refrigerator space through said tube 12, and the latter is sui-mounted bythe cap 1a which is largerr in' diameter than said tube, including the insulation thereabouts. rlhis cap rests in any desired manner upon the upper end of the tube as by the depending clip 15, sorthat the lower edges of the can project considerably below the upper end or the tube and its insulation; thus providing a space about the tube which acts as a water seal and yet will permit of the brine overflowing into the tube when it rises above the end thereof.

The drain tube is just sufficiently high to maintain a level of brine some distance below the bottom 9 of the display space so that air may circulate forwardly beneath the bottom 9 and upwardly through the perforated grid or screen 16 which spans the space between the forward edge of the bottom 9 and the inwardly arched moulding 17 of the front corner of the show case.

There is shown at 18 a drain plug which opens into the upper end of the drain tube so that in the event of wishing todrain all of the brine from the case, the saine may be accomplished .by the removal of the plug 18.

rThis novel arrangement is for the particular purpose of convenience in assembling the brine tank within the show case, as the same is shoved into the case from the back during construction, thus having a flush bottom with both discharge openings therein oc curring directly above the tube 11, insuring drainage thereof through said tube.

It is apparent that any refuse flowing down the bottom 9 with the moisture returning, into the brine tank will be caught on the grid 16 in back of the inouldino' 17 where it will not be. conveniently seen p. roni the front of the show case. rlhe rearinost edge of the bottom or shelf 9 isl supported by horizontally spaced upright brackets 19 and the back wall 2O of the show space. is supported upon thesebraclrets and preferably carries a mirror 21 therein. This back wall 90 terminates short of the upper corner intermediate of the inclined back of the show space and the top of the refrigerator space so as to permit ofready air circulation therethrough.

From the above it is apparent that when ice with salt is placed within the refrigerator space it will forni a brine that will extend entirely across the lowerniost portion of theV refrifferator space beneath the display space and that the cold air thus formed will natu- Vtlf) rally circulate upwardly through the grid 16, thence upwardly and backward-ly into the upper edge of the display space indicated at 7.

Having thus described my invention, what I claim and desire to secure by Letters Patent, is:

l. A refrigerated show case of the character described includingr a front Wall coinprising an upper transparent portion and a lower opaque portion, a `grid adjacent and concealed from View by said opaque. Wall, and an elevated floor inclined toward sai-d grid so as to. drain therein substantially as and for the purpose described.

2. A show case. of thec-haracter described including a display compartment, an elevated floor therebeneath, a downwardly stepped grid adjacent the forward edge of the. iioor, a refrigerant containing tankv extending beneath said floor and rearwardly thereof, said tank having. an' upstanding Water sealed drain pipe and aV funnel shaped drain tube in the bottom proper oi the show case for registration With the drain tube in the refrigerant tank, and a plu-g for said drain tube.

In testimony whereof I hereunto affix iny signature. ,Y
